Probably the best battery possible for a tipping trailer. Have previously killed multiple leisure batteries, but bought this one following advice from Tayna and couldn't be happier. It has an amazing capacity and never misses a beat.

The team member I spoke to was really helpful and efficient, easily found the battery I needed and helped me place the order, which arrived quickly and well packaged. So far the battery is doing its job, and has given my Wrangler a new lease of life.
